Robert Pattinson buzzed off his hair ... but only half of it!
The "Twilight" star showed off his bizarre new look today at the "Breaking Dawn" panel for Comic-Con, where he answered questions about the final movie alongside co-stars Kristen Stewart and Taylor Lautner.
The crazy look is for Pattinson's post-"Twilight" flick "Cosmopolis," but that's not what had fans shrieking in Hall H.
According to the Hollywood Reporter, the Twi-hards went crazy when fans were treated a honeymoon scene -- which "garnered breathless screams after almost every line."
